David Scopelliti and Tom Keck, both managing directors and management committee members, left Pacific Corporate Group, confirmed Owen Blicksilver, spokesman for Messrs. Scopelliti and Keck. Mr. Scopelliti had been with the firm for six months; Mr. Keck had joined the firm in August 2005. David Fann, managing director, will assume Mr. Keck's duties as head of research, said a PCG spokesman who declined to be identified. The spokesman had no further information on replacements, including whether Messrs. Scopelliti and Keck would be replaced on PCG Asset Management's four-person management committee. The firm has now lost seven top executives since September. Christopher Bower, PCG founder and CEO, could be reached for comment by deadline. Messrs Scopelliti and Keck are evaluating their options, including the potential of doing something together, Mr. Blicksilver said.
